Purpose: With the increasing national interest in health, the number of health examination centers is growing rapidly, and it is growing as independent medical institutes separated from hospitals. With the growing functions and size of health examination institutes, considerations for testees, who are the most important users of the health examination centers, have taken the back seat. In particular, for health examination programs that take on a sequential traffic line, it is important to be aware of the space of each examination room, but the lack of a scientific evaluation method for this has resulted in great discomforts for testees using the health examination center. Method: Thus, this study proposes risk evaluation indices (RCF TCF, RC3, RR, ARR), and set a standard health examination program based on the national health examination program. This was applied to 11 different sized health examination centers to find their features, and together with identifying the trends of the indices, the following results were deduced. Result: 1) ARR showed a wide-range feature as the number of unit spaces increased, while RR were discovered regardless of the size, thus displaying local features. 2) The increase of ARR is affected more by internal factors in the health examination center than from outside factors. 3) By gender, when separating the basic health examination fields, the connective relation of the comprehensive health examination fields had a big effect on ARR. 4) By becoming larger, the fields of function become independent and the waiting space that results from it increases the number of total movement, so there is space for improvement in this.

Wellbeing is a new trend to modern people and Spa facilities are an appropriate space to them seeking a wellbeing life. Spa facilities will be increased in demand as a value of a public welfare and wellbeing life and the study of them is required. Therefore this study was to analysed domestic and foreign spa programs and characteristic spaces. When synthesizing many spa programs they were divided into three parts: hydrotherapy as a healing therapy using water, touch therapy as a type of massage using a manual and subsidiary equipment and mind therapy to heal spirit. Space of spa facilities were divided into three parts: the supporting part, the relaxing and mediating parts and the room for therapy. The supporting parts included a front desk, a consulting room, lockers, bath room and acceptance rooms etc and they were arranged in entrance space generally. The rooms for therapy were composed with a room for hydrotherapy using water, rooms for touch therapy and rooms for mind therapy refreshing a spirit and they were established contiguously being used efficiently. The mediating parts provided spaces for relaxation and waiting place between therapies and they were established in independent space generally but they are paid attention at good spaces forming the community of visitors and giving a characteristic images for the spa. Spa has been divided into several types in accordance with age of visitors for example children, young people, middle aged people and aged people. It has equipped with complex functions from welfare to medical. Therefore it is thought that many studies of each facilities become accomplished to propose suitable interior design.

환적화물 유치를 위해 전 세계 항만 간의 경쟁이 심화되고 있다. 하지만, 최근 중국의 해운부문 카보타지 정책 해제, 안전운임제시행 등 국내 항만의 환적화물 물동량 이탈이 우려되는 상황들이 발생하고 있다. 운영적 측면에서도 터미널별 환적 물동량의 불균형, 특정 시간대에 집중된 차량 등으로 인해 터미널 혼잡 및 차량 대기시간 문제가 심각하게 나타나고 있다. 본 논문에서는 타부두 환적운송 시스템으로 인해 발생하는 차량 대기시간 문제를 해결하기 위해 완충지역을 활용한 타부두 환적 컨테이너 운송 방식을 제안하고 문제에 대한 혼합정수계획 모형을 제시하였다. 부산 신항 데이터에 기반한 터미널 혼잡 패턴과 터미널간 운송 차량 반출입 패턴을 적용하여 다양한 작업량, 가용량 변동폭에 대해 완충지역 활용에 따른 효과를 분석하였다.

The purpose of this study is to suggest a scheme to provide children safer and more comfortable walking circumstances by survey current walking circumstances of schoolzone ways. A scheme suggested in this study was based on the analysis of survey to elementary school in 3 Newtowns(Dongtan, Dongbaek and Gumdan City) and actually surveyed data on school zone, the scheme can be summed up as follows; First, to avoid pedestrian roads being interrupted and to expend waiting space near schoolzone ways, several measures are needed including fixing roads and building additional gateway. Second, pedestrian crossings in front of school gate should be located at least 30m away from the left side of the gate. Third, to secure pedestrians' safety in school zone ways should be planed and established more security concepts und facilities.

The aim of this paper is to analyze the batch service queueing model M/M(a, b ; ${\mu}_k/1$) under general bulk service rule with mean service rate ${\mu}_k$ for a batch of k units, where $a{\leq}k{\leq}b$. This queueing model consists of the two-dimensional state space so that it is characterized by two-dimensional state Markov process. The steady-state solution and performane measure of this process are derived by using Matrix Geometric method. Meanwhile, a new approach is suggested to calculate the two-dimensional traffic density R which is used to obtain the steady-state solution. In addition, to determine the optimal service initiation threshold a, a decision model of this queueing system is developed evaluating cost of service per batch and cost of waiting per customer. In a job order production system, the decision-making procedure presented in this paper can be applicable to determining when production should be started.

The purpose of this study is to suggest architectural planning guideline for the improvement of the evacuation environment in a ward. To suggest of guideline, the problem of irrational domestic criteria is searched according to compare National fire code (NFPA101, Life safety code) with Korea building law. This study includes stairs, corridors and exit door etc. but excludes fire facilities. To verify effectiveness of suggested guideline, egress simulation is run that based on databases according to literature survey. The results of this study could be summarized as follow: Suggested guidelines are subdivision(fire partition), evacuation by elevator, secure useful waiting space of elevator hall and smokeproof enclosures, the corridor is divided by fire or smoke barriers corridor from hazardous room, only wheeled items are arranged in corridors of a ward story. The result of computer simulation for suggested guidelines verify that egress time can be decreased 20% or above.

The purpose of this study is to suggest a scheme to provide children safer and more comfortable walking circumstances by survey current walking circumstances of school zone ways. First, to avoid pedestrian roads being interrupted and to expand waiting space near school zone ways, several measures are needed including fixing roads, using schools' unemployed spaces and building additional gateway. Second, pedestrian crossings in front of school gate should be located at least 23.16m away from the left side of the gate. Third, on narrow path which cross main streets, the interval of pedestrian signal should be extended as against of the moment. And traffic calming facilities should be built on accurate position. Fourth, to secure pedestrians' safety and field of view, trees lining streets and any obstacles located within 10m from bus stop sign should be removed. Finally, education system about school zone ways should be improved to help children get used to more complicated roads' conditions.

Soundscape design is applied for the purpose of expressing the characteristics of places, by supplying suitable background sound for various places expressing their identity. Bus stations are a place for aggregating people using transportation. That is, people go into a station, buy a ticket, and wait for departure or for other passengers. Therefore, they need to create a more comfortable sound environment. This study aims to make bus stations a comfortable place acoustically for users. In this study, analysis on behavior at various locations in the space was performed. Measurements were taken on the approaching path, waiting place, departure and arrival platforms for sound levels and frequency characteristics. In addition, on acoustic specialists evaluation, using questionnaires, was also performed ambient noise, information broadcasting and users dialogue.

In this paper we propose an approximation analysis for the system size distribution of the M/G/c system which is transform-free,. At first we borrow the system size distribution from the Markovian service models and then introduce a newly defined parameter in place of traffic intensity. In this step we find the distribution of the number of customers up to c. Next we concentrate on each waiting space of the queue separately rather than consider the entire queue as a whole. Then according to the system state of the arrival epoch we induce the probability distribution of the system size recursively. We discuss the effectiveness of this approximation method by comparing with simulation for the mean system size.
